SUMMARY:Stefano Soleti (Oxford/Harvard U.) "Searching for a Low-Energy Excess at MicroBOONE"
DESCRIPTION:ABSTRACT:\nThe last twenty years have seen a spectacular improvement in our understanding of neutrino oscillations and neutrino physics in general. However\, several experiments have shown some puzzling results which do not fit the standard three-flavor mixing scheme of neutrinos. In particular\, the LSND and MiniBooNE experiments observed an excess of low-energy electron neutrinos\, which could be interpreted as the signature of a fourth\, non-weakly interacting\, neutrino. The goal of the MicroBooNE experiment\, a liquid argon time projection chamber currently running at Fermilab\, is to assess the nature of this excess. In this talk the first automated electron neutrino search in a LArTPC will be presented. This result is the first step towards a measurement of the low-energy excess at MicroBooNE.

SUMMARY:Cheng-Ju Stephen Lin (LBNL) " ProtoDUNE: Path Towards Building the Largest Liquid Argon Neutrino Detectors"
DESCRIPTION:Abstract:\nA large international collaboration has been formed to carry out an ambitious project to build the Deep Underground Neutrino Experiment (DUNE) for investigating fundamental questions in neutrino and proton decay physics. The DUNE far detector consists of four time-projection chambers (TPC) filled with 70\,000 tons of liquid argon. It wil by far be the largest liquid argon neutrino experiment ever built. The ProtoDUNE experiment aims to validate the design and construction of the DUNE far detector by operating two kton-scale prototype detectors in a charged-particle beam at CERN. These two detectors will help assess different technologies for TPC ionization drift and readout (single and dual phase TPC) that are being considered in DUNE. In this talk I will discuss the challenges of building the large prototype detectors and present some preliminary results from operation of the single-phase ProtoDUNE detector.

SUMMARY:Joannes Lange (Yale) "Probing Galaxy Formation and Cosmology in the Non-Linear Regime"
DESCRIPTION:Abstract:\nCurrent and future galaxy surveys have the potential to transform our understanding of both galaxy formation and cosmology. The distribution of galaxies and matter on small\, non-linear scales (~Mpc) holds the most statistical constraining power but is also the most challenging to model. In this talk\, I will concentrate on three distinct probes on small scales: galaxy clustering\, galaxy-galaxy lensing and satellite kinematics. I will present new measurements of the tension between clustering and lensing in the BOSS survey. The most promising explanations for this tension\, baryonic feedback\, assembly bias and cosmological parameters different from the Planck CMB constraints\, are discussed. Furthermore\, I will present an updated\, more robust analysis to extract constraints on the galaxy-halo connection from satellite kinematics. The accuracy of this approach is tested using a large number of realistic mock catalogs and shown to yield unbiased\, highly competitive constraints. I then apply this updated analysis to the SDSS survey and compare the inferences from satellite kinematics to those from previous studies. Finally\, I will discuss future directions for modeling non-linear scales which will allow to unlock the full potential of upcoming surveys like DESI or LSST.

SUMMARY:Ximo Poveda Torres (CERN) " The Top-Higgs Connection: Measuring ttH Production with the ATLAS Experiment
DESCRIPTION:Abstract: \nThe measurement of the Yukawa coupling of the top quark and\nthe Higgs boson\, namely the two most massive fundamental particles\nobserved so far\, is a crucial piece for understanding the mechanism of\nfermion mass generation. The most promising way to directly probe this\ncoupling is by measuring the Higgs boson production in association with\na top quark pair (ttH). ATLAS recently observed ttH production using\n√s=13 TeV LHC pp collision data\, exploiting several Higgs boson decay\nchannels. Current ttH results will be summarized in this seminar\, and\nprospects for future measurements will also be discussed.

SUMMARY:Jose Luis Bernal (Barcelona U.) "Synenergies and Fundamental Physics from the Large Scale Structure
DESCRIPTION:Abstract: \nGalaxy surveys and the study of the Large Scale Structure (LSS) have played an important role in establishing the standard cosmological model\, LCDM\, and will push the envelope of observational cosmology the next decades\, thanks to experiments such as DESI and Euclid. In this talk\, I will show how we can use LSS observations and techniques to address the tension in the Hubble constant\, the origin of supermassive black holes and the nature of dark matter.\n \nFurthermore\, the ever larger volumes surveyed by next-generation galaxy surveys will enable access to the ultra-large scales\, where signatures of General Relativity and inflation are significant. This will allow us to probe the nature of gravity and the very first instants of the Universe\, but also requires a very specific methodology\, which I will discuss during the talk.
